| Abstract | ||
| :A new series of Schiff bases were obtained by condensation of 3- methoxy -4-hydroxy benzaldehyde (vanillin) with seven aromatic amine .These bases were identified by infrared spectra and melting point . The effect of the substituents (x) on the amino ring has been studied. The charge transfer complexes (CTC) of the Schiff bases as a donor molecules with various electron acceptors as(DDQ ,P-CA ,O-CA ,-m-Dn and PF (used for the first time as acceptor) in methylene chloride and methanol (solvent ) were estimated , the physical parameters of the CT complexes were calculated by applying the Benesi –Hildebrands equation for 1:1 CT complexes .The study also involved precipitation of one Schiff bases (1)with three electron acceptors as CT complexes and identified these complexes by IR ,melting point, UV-visible and the colures . | ||
